I believe these are Czech. The pattern is shown (in a range of sizes) in thirties Markhbeinn catalogues (available from Pressglas-korrespondenz.de) - Markhbeinn was a French company who imported/ sold a lot of Czech glass. In the past, i've seen this shape attributed to Riedel, but I think Inwald may be more likely. Hopefully Marcus or Jindrich may be able to add more.

yeah just found it in the Rudolfova Hut catalogue its Pattern number: 11558/A although it doesnt state who designed it. So as mosquito said Marcus or Jindrich will be able to fill in the gaps with the correct info
